locking and unlocking positions; and when Be it known that l[, THOMAS C.S'raLnY, a l the bolt f has been arranged in its locking citizen of theUnited States, and a resident of Portland, in the county of Multnomahand State of Oregon, have invented a new and useful Improvement inWindow-Sash Locks, of which the following is a specification.

This invention has for its object to provide an inexpensive and.effective means for locking the upper and lower sashes of a win dowtogether, at variable height, in such wise that the window may be movedup or down to obtain an air-inlet under the lower sash, or over the topsash, but preventing the separation of the window-sashes and thusexcluding entrance into the room therethrough.

i carry my invention into effect by the means illustrated in theaccompanying drawings in which:

Figure 1 is a partial, vertical section of the top and bottom sashes ofthe window, arranged in their closed position and locked together bymeans of my lock; Fig. 2 is an inside elevation corresponding with Fig.1; Fig. 3 is a plan section, taken on a line 02-:0 of Fig. 1, butapproximately life or actual size, showing my device aranged to lock thesashes together, as shown in Fig. 1; and Fig. 4: is a like section asFig. 3, but on a scale agreeing with I igs. 1 and 2, showing my lock inits open position.

The letters designate the parts described.

a, 6 represent the top and bottom sashes, respectively, of a window. Tothe inner, vertical face of the side rail of the top sash is fastened anangleiron c, of any convenient length, with one leg perforated toreceive screws by which to fasten it to the rail of the sash, and theother leg 0 being pro vided with a series of holes (Z, placed suitabledistances apart.

To the top-side of the meeting rail of the lower sash Z) is atlixed mylock. My lock comprises a plate 6, on which is pivoted a rotatablemember or bolt 7, provided with a bill or horn g, the outer curve ofwhich bill is described from the center of the pivot-pin, while theinner curve thereof is described from a difierent center, so located asto make the horn or bill 7 wedge-shaped; or in other words, widening asit recedes from the point. To the main body of the rotatable member orbolt 7 is pivoted a handle h, so as to ten der it convenient to rotatethe bolt 7* into its position, the handle it may be lifted and droppedin front of the horn g of the bolt 7, and thus prevent the retraction ofsuch born from engagement with the angle-iron c. rsaw kerf is madethrough the lip of the meeting rail of the lower sash in alinement withthe projecting rib c of the angleiron 0, so as to permit the lower sashto be raised and lowered over said angle-iron.

The operation of arranging my device to lock the window-sashes isillustrated in Fig. 3. The horn g enters one of the perforations of theleg 0 of the angle-iron c, and by then pressing against the handle, soas to force the horn g as much as possible through the perforation ofthe angledron which ithas entered, the meeting rails of the two sasheswill be firmly locked; and, furthermore, the two sashes will be drawntogether, as it were, and rattling prevented. After having arranged mydevice in its locking position, the handle it is lifted and dropped infront of the point of the horn g, as shown in dotted outline in Fig. 3.To unlock the sashes, it is only necessary, as self evident, tore-arrange the handle it in its projecting position and rotate the bolt7 in a reverse direction.

The holes cl of the leg 0 of the angle-iron a may be spaced apart anyconvenient distance, so as to allow the sashes to be interlocked by mydevice in such wise as to provide a limited opening, insuflicient for aperson to crawl through, and yet providing ample ventilation. And thetwo interlocked sashes may then be arranged to give all the opening atthe bottom or at the top of the window, or part of the opening at thebottom and part at the top, as deemed expedient.

I claim:

A. window lock comprising a rotatable member provided with a curved billadapted to be engaged with a suitable keeper, and a handle pivoted tothe rotatable member and adapted to be arranged in projecting positionand to be dropped in front of said bill of the rotatable member toprevent the dis engagement of the latter when locked with suchperforated bar.
